Technical Abstract

One or more pages are displayed on a touch display. A page-turning gesture directed to a displayed page is recognized. Responsive to such recognition, a virtual page turn is displayed on the touch display. The virtual page turn actively follows the page-turning gesture. The virtual page turn curls a lifted portion of the page to progressively reveal a back side of the page while progressively revealing a front side of a subsequent page. A lifted portion of the page is given an increased transparency that allows the back side of the page to be viewed through the front side of the page. A page-flipping gesture quickly flips two or more pages.

Patent Claims
20 claims

Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.

Claim 1

Original Legal Text

1. A digital reading device, comprising: a touch display; a logic subsystem operatively coupled to the touch display; and a data-holding subsystem holding instructions executable by the logic subsystem to: display a front side of a page on the touch display; recognize a page-turning gesture directed to the page on the touch display; and display a virtual page turn that actively follows the page-turning gesture, the virtual page turn curling a lifted portion of the page to progressively reveal a back side of the page while progressively revealing a front side of a subsequent page, the lifted portion of the page having an increased transparency that allows the back side of the page to be viewed through the front side of the page.

Plain English Translation

A digital reading device has a touch display and a processor. The processor runs software to show a page on the display. When the user swipes to turn the page, the device shows a virtual page turn animation. The animation curls the corner of the page that the user touched, revealing the next page underneath. The curled portion of the page becomes transparent, so you can see the back of the current page through the front.

Claim 2

Original Legal Text

2. The digital reading device of claim 1 , were a corner of the page tracks an object performing the page-turning gesture as the object moves across the touch display.

Plain English Translation

In the digital reading device described in claim 1 (a device with a touchscreen that simulates page turns with a curl animation and transparency), the corner of the page visually sticks to the user's finger as they drag it across the screen, making the page turn feel more realistic. The on-screen corner moves in direct response to the finger movement.

Claim 3

Original Legal Text

3. The digital reading device of claim 1 , where the virtual page turn further curls the lifted portion of the page to progressively cover a back side of an opposing page.

Plain English Translation

In the digital reading device described in claim 1 (a device with a touchscreen that simulates page turns with a curl animation and transparency), the curled portion of the page also progressively covers the back of the previous page as it turns, hiding the old page.

Claim 4

Original Legal Text

4. The digital reading device of claim 3 , where the lifted portion of the page progressively covers the back side of the opposing page responsive to an object performing the page-turning gesture moving over a portion of the touch display that was displaying the opposing page.

Plain English Translation

In the digital reading device described in claim 3 (a device with a touchscreen that simulates page turns, curling the page to reveal the next and cover the previous), the curled portion of the page starts covering the back of the previous page when the user's finger moves over the area of the screen where the previous page was displayed. The area covered is determined by the finger's movement.

Claim 5

Original Legal Text

5. The digital reading device of claim 3 , where the virtual page turn substantially fully covers a back side of the opposing page and substantially fully reveals the subsequent page if the page-turning gesture advances to completion.

Plain English Translation

In the digital reading device described in claim 3 (a device with a touchscreen that simulates page turns, curling the page to reveal the next and cover the previous), if the user completes the page-turning gesture, the curled page completely covers the back of the previous page, and the next page is fully displayed.

Claim 6

Original Legal Text

6. The digital reading device of claim 1 , where the data-holding subsystem further holds instructions executable by the logic subsystem to: recognize a reversal in the page-turning gesture; and responsive to the reversal in the page-turning gesture, display a virtual page return that actively follows the page-turning gesture, the virtual page return uncurling a lifted portion of the page to progressively conceal a back side of the page while progressively concealing a front side of the subsequent page.

Plain English Translation

In the digital reading device described in claim 1 (a device with a touchscreen that simulates page turns with a curl animation and transparency), if the user reverses the page-turning gesture, the device shows a "page return" animation. The animation uncurls the page, hiding the next page and re-revealing the original page. The animation actively follows the user's reversed gesture.

Claim 7

Original Legal Text

7. The digital reading device of claim 1 , where the data-holding subsystem further holds instructions executable by the logic subsystem to: recognize a page-flipping gesture directed along an outer edge of the touch display; and display, responsive to advancement of the page-flipping gesture, an accelerated flipping of pages.

Plain English Translation

In the digital reading device described in claim 1 (a device with a touchscreen that simulates page turns with a curl animation and transparency), when the user swipes along the edge of the screen, the device recognizes this as a "page-flipping" gesture and quickly flips through multiple pages.

Claim 8

Original Legal Text

8. The digital reading device of claim 1 , where the data-holding subsystem further holds instructions executable by the logic subsystem to: recognize a shortcut in the page-turning gesture; and responsive to the shortcut in the page-turning gesture, accelerating the virtual page turn ahead of an object performing the page-turning gesture to quickly complete the virtual page turn.

Plain English Translation

In the digital reading device described in claim 1 (a device with a touchscreen that simulates page turns with a curl animation and transparency), if the device detects a "shortcut" in the page-turning gesture (for example, a very fast swipe), it speeds up the virtual page turn animation to quickly complete the turn, even faster than the user's finger is moving.

Claim 9

Original Legal Text

9. The digital reading device of claim 1 , where the increased transparency of the lifted portion of the page further allows the front side of the page to be viewed through the back side of the page.

Plain English Translation

In the digital reading device described in claim 1 (a device with a touchscreen that simulates page turns with a curl animation and transparency), the transparent effect on the curled portion of the page allows you to see both the back and front of the page at the same time.

Claim 10

Original Legal Text

10. A method of operating a computing device having a touch display with a first touch display region and a second touch display region, the method comprising: displaying a back side of a first page on the first touch display region and a front side of a second page on the second touch display region; recognizing a page-turning gesture directed to an outer corner of the second page; and displaying, responsive to the page-turning gesture, a virtual page turn that actively follows the page-turning gesture, the virtual page turn curling a lifted portion of the second page to progressively reveal a back side of the second page while progressively revealing a front side of a third page and while progressively covering the back side of the first page, the lifted portion of the second page having an increased transparency that allows the back side of the second page to be viewed through the front side of the second page.

Plain English Translation

A method for a computing device with a touch screen is described. The device displays the back of one page on one area of the screen and the front of the next page on another area. When a user touches and swipes the corner of the second page, a realistic page-turning animation starts. The corner of the page lifts and curls, progressively showing the back of that page and the front of the following page, while simultaneously covering the back of the previous page. The lifted corner has a see-through effect, showing both sides of that page at once.

Claim 11

Original Legal Text

11. The method of claim 10 , were the outer corner of the second page tracks an object performing the page-turning gesture as the object moves across the first touch display region and the second touch display region.
